High temperature resistant epoxy resins for producing hollow fiber membrane modules for high temperature gas separation applications

摘要

The present invention provided a high temperature resistant epoxy resins for producing hollow fiber membrane modules for high temperature gas separation applications such as for natural gas upgrading and hydrogen purifications. This invention also relates to a hollow fiber membrane module comprising a bundle of multiple high performance hollow fiber membranes and a tube sheet formed by a high temperature resistant cured epoxy resin that is used to fix and bound said bundle of multiple high performance hollow fiber membranes. The invention also provides a process for separating at least one gas from a mixture of gases using the hollow fiber membrane modules comprising a bundle of multiple high performance hollow fiber membranes and a tube sheet formed by a high temperature resistant cured epoxy resin that is used to fix and bound said bundle of multiple high performance hollow fiber membranes.
